## Installation
Install the stable release from CRAN:
```r
install.packages("qqman")
```
Or install directly from github using devtools
```r
library(devtools)
install_github("stephenturner/qqman")
```
Or install the most recent development release with devtools (note, there be dragons here):
```r
library(devtools)
install_github("stephenturner/qqman", ref="dev")
```
Load the package each time you use it:
```r
library(qqman)
```
## Usage
See the [online package vignette](https://cran.r-project.org/package=qqman/vignettes/qqman.html) for more examples:
```r
browseVignettes("qqman")
```
Take a look at the built-in data:
```r
head(gwasResults)
```
Basic manhattan plot using built-in data:
```r
manhattan(gwasResults)
```
Basic Q-Q plot using built-in data:
```r
qq(gwasResults$P)
```
Get help:
```r
?manhattan
?qq
```
## Notes
* This release is substantially simplified for the sake of maintainability and creating an R package. The old code that allows confidence intervals on the Q-Q plot and allows more flexible annotation and highlighting is still available at the [version 0.0.0 tag](https://github.com/stephenturner/qqman/tree/v0.0.0).
* Special thanks to Dan Capurso and Tim Knutsen for useful contributions and bugfixes.
* Thanks to all the blog commenters for pointing out bugs and other issues.
